This issue has persisted since the time you started supporting utorrent on nzb360.
So what happens is let's say I am on Sonarr and use volume rocker key to goto uTorrent page, it says connection error with a retry button. As soon as I press the retry button the torrents are polled. Now I move away and come back to torrents page again, same thing will happen. I will have to manually click retry.
Video for the same shared over email.
P.S: doesn't matter it's volume rocker or manually selecting from navigation bar same torrent connection error will occur.
Putting the bug here so it will be easier for you to track.
